[vtkusers] Procedure Entry Point not found

[David Gobbi]

Hi Alexis,

If the error you are getting is still about CollectRevisions, then no.
First you have to make sure that the vtkSonixVideoSource class was
properly rebuilt, and you have to make sure that the PATH is set
properly when you run your code, i.e. check to make sure that the
correct DLLs are being used when you run the program.
